WALTER G. FRAZEUR, OF TOPEKA, KANSAS.

GAS-BURNER.

To all whom. it may concern:

Be it known that I, WALTER G. FRAZEUR, a citizen of the United States,residing at Topeka, in the county of Shawnee and State of Kansas, haveinvented a new and useful Improvement in GasBurners, of which thefollowing is a specification.

The invention relates to gas burners adapted for use in stoves,furnaces, and the like; and is especially adapted to be put into anyordinary coal stove or furnace in converting the stove or furnace to theuse of gas, instead of coal, as fuel. The invention is therefore a gasburner attachment for stoves, furnaces, and he like, and adapted for usein connection therewith.

Objects are: to improve generally upon gas burners, and as well upon gasburner ati'aclnnents for stoves, furnaces, and the like; to simplify theconstruction of the burner itself, and also to provide a gas burnerwhich may be more easily applied to an ordinary stove or furnace inconverting same to the use of gas; to provide a burner adapted toproduce a greater radiation of heat to the bottom portions of the stovethan has heretofore been possible; to provide a burner whiclrthrows theflame downwardly and outwardly against the bottom and sides of thestove, in order to secure greater radiation from the lower part of thestove and thus prevent loss of heatthrough the flue; to provide a burnerin which all the outlets shall be through the bottom and the inlet shallbe from above.

The invention consi; of the parts, improvements, and combinations hereinset forth and claimed.

in the drawings accompanying and forming part .of this specification andin the description thereof, I have shown my invention in its preferredform and the best mode of applyin the principles thereof; but it is tobe understood that I contemplate changes in form, proportions, andmaterials, the transportation of parts, and the substitution ofequivalent members without departing from the spirit of the invention.

Figure 1 is a center sectional view of an improved gas burnerconstructed in accordance with my invention, showing a detached portionof the gas inlet pipe. Fig. 2 is a top view, and Fig. is a bottom view,of the burner.

corresponding parts throughout the several views.

4 is a circular plate having convex upper and concave lower sides; and 5is a centrally disposed opening into which the inlet pipe 11 may befitted.

6 is a circular plate of about one-half the diameter of the larger platea, and having concave upper and conyex lower sides. The two plates aresecured together with their concave faces together by means of a numberof bolts 7, 7, 7. Around the edge of the smaller plate are a number ofnotches which form slits S, 8 when the two plates are secured together;also the smaller plate is perforated 9, 9, and is provided on itsconcave side with a centrally disposed domelike deflector 10. hen theplates are fastened together as described, a chamber is formed betweenthem, to which the opening 5 forms an inlet and the slits 8 andperforations 9 form the outlets. It is an essential part of thisinvention that the large plate shall be above and the smaller platebelow, and that the outlets shall be through the underside of theburner. It is preferable that the inlet shall be through the top plate,and it is important that said inlet 7 shall be centrally disposed. Theinlet pipe 11 may obviously be the mixer commonly used in gas-burners.

As the upper parts of the stove or furnace are usually made of thinnermaterial than the lower parts, and as they are also more accessible, itis easier to attach my improved burner to a stove or furnace than it isto attach a burner in which the gas is brought in from underneath. lVithmy improved burner all the flame is directed downwardly against thebottom portion and outwardly against the sides of the stove; instead ofoutwardly and upwardly; and hence a greater proportion of the heat isradiated to the lower portions of the stove. Also by diverting all theflames around the edge of the large plate the flames are directedagainst the sides of the stove. I thus avoid the necessity of thecumbersome heat retainers, the burner itself may be made of lightermaterial, the danger of the fire accidentally going out is much reduced,and the radiation to the lower part of the stove is made more directfrom the flame than where the flames are directed outwardly andupwardly. The concave lower face of the large plate is material for thepurpose of confining and directing the flame and heat downwardly. Thedischarge openings being all through the under side of the burner, theyare not liable to become obstructed with dirt or foreign matter fallingtherein from the outside.

\Vhat I claim is:

1. A gas burner attachment for stoves, furnaces, and the like,comprising a circular upper plate having convex upper and concave lowersides and a centrally disposed opening; an inlet gas pipe fitted fromabove into said opening; a perforated circular lower plate of smallerdiameter than the upper plate, having concave upper and convex lowersides, and having a series of notches or slits around its edge; adomelike deflector centrally disposed on the concave side of the lowerplate; and bolts for securing said two plates together; said two platesbeing secured together concentrically with their concave faces togetherand forming a chamber between them to which said opening forms the inletand said perforations and slits form the outlet.

2. A gas burner attachment for stoves, furnaces, and the like,comprising a circular upper plate having convex upper and concave lowersides; a perforated circular lower plate of smaller diameter than theupper plate, having concave upper and convex lower sides, and having aseries of notches or slits around its edges; said two plates be ingsecured together concentrically with their concave faces together andforming a chamber between them; a gas pipe leading concentrically intosaid chamber, and a dome-like deflector within said chamber and oppositesaid inlet gas-pipe.

3. A gas burner attachment for stoves, furnaces, and the like comprisingthe combination of a circular upper plate and a circular lower plateconcentrically secured together with a chamber therebetween; an

inlet pipe leading into said chamber, and gas outlets arranged aroundthe outer edge of the lower plate and below the upper plate; the upperplate being of larger diameter than the lower plate, and its undersurface beyond the edge of the lower plate extending outwardly in agentle downward slope from said gas outlets.

A gas burner attachment for stoves, furnaces, and the likecomprising'the combination of a circular upper plate and a circularlower plate, bolts securing said plates concentrically together with achamber therebetween; an inlet pipe leading into said chamber, andoutlets arranged around the outer edge of the lower plate and below theupper plate; the upper plate being of larger diameter than the lowerplate and forming a broad flange extending out beyond the edge of thelower plate, and the under surface of said flange forming a guide forthe burning gas extending ontwardly and slightly downwardly from saidgas outlets.

5. A gas burner attachment for stoves, furnaces, and the like comprisingthe combination of an upper and a lower plate secured together with achamber therebetween; an inlet pipe leading into said chamber, and gasoutlets at the edge of the lower plate and under the upper plate, saidupper plate extending out beyond the lower plate and forming a broadflange extending out beyond the gas outlets, the under face of saidbroad flange forming a guide for the burning gas extending outwardly andslightly downwardly from said gas outlets.

In testimony whereof, I have hereunto signed my name in the presence ofwitnesses.
